OIL-CAN.

Application filed December 11, 1915.

' To all whom it may concern Be it 'known that I, JoHN C. POTTER, a citizen of the United States, residing at Alexandria, in the county of'Hansonand State of South Dakota, have invented certain new and useful Improvements in Oil- Cans; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. 7

This invention relates to new and useful improvements in oil cans, and has for one of its objects the provision of a device of the above stated character, which shall be simple, durable and eflicient and which may be manufactured and sold at a comparatively low cost.

A further object of this invention is the pro-vision of an oil can having a flexible bottom for the purpose of forcing lubricating liquid from the can by pressing inwardly upon the flexible bottom. c w

A further object vof this invention is the provision of an oil can having a flexible and elastic bottom with a spring pressed standard mounted within the oil can to bear upon the center of the bottom to force it outwardly after it has been pressed inwardly to expel the lubricating liquid, whereby the can will not be rendered unfit for use should the bottom lose its elasticity. A still further and more specific object of this invention, of the above stated character, isthe provision of novel means for supporting the standard in a vertical position within the oil can and in engagement with the central portion of the flexible body and resiliently attached to thelower end of the spout of the can, providing a central pressure upon the flexible bottom at all times.

With these and other objects in view, as will become more apparent as the description proceeds, the invention consists in certain novel features of construction, combination and arrangement of parts as will be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawing, in which:

Figure 1 is a side sectional elevation, showing the standard resiliently connected to the lower end of the spout of an oil can and bearing upon the central portion of the Specification of LettersPatent.

Serial No. 66,316.

flexible bottom, and Fig. 2 is a horizontal sectional view, taken onthe line 22 of Fig. 1, looking in the direction of the arrow, showing the connection betweenthe flexible bottom and the standard.

Referring tothe drawing in detail, the numeral 1 designates the side walls of an oil can, having a flexible bottom 2 secured thereto, and the upper edges of the walls 1 being bentinwardly and inclined upwardly, as at 3, to form a vertical flange' l, providing a mouth to the oil can. The flange 4:

screw threads iscrimped to form internal 5 to receive a cap 6 provided with a reduced portion having external screw threads 7 thereon to be received within the vertical 11 intermediate its length to receive one end of a standard of wood, or other suitable flange 4. A spout 8 is secured cent-rally material, 12,which engages the fiexible bot tom 2. The lower end of the standard 12 is slotted to receive a pin or wedge13 to secure and firmly hold the standard in the opening 11 of the supporting strip 10 and in a vertical position within the oil can- The standard 12 is provided with an enlarged portion adjacent the upperend thereof to provide a shoulder 14, said standard 12 being reduced, as illustrated'at 15, from the shoulder 14 to the upper terminal of the standard and provided with external screw threads to receive a coupling sleeve 16, which will be hereinafter more fully described.

The coupling sleeve 16 consists of an outer vertical wall 17 and an inner parallel wall 18, said wall 18 being crimped to form internal screw threads thereon and secured to the wall 17 by means of a horizontal wall 19, forming a pocket 20. The upper edge of the wall 17 is bent at right angles to form a flange, having'corrugations 21 thereon to facilitate the screwing of the coupling sleeve 16 upon the standard 12 to adjust the tension of a coil spring 22 which is received within the pocket 20 and secured to the walls 17 and 18 by soldering or other suitable means. The coil spring 22 is in turn secured to the interior of a spout 8 by solder, or other suitable means, to form a resilient the 1 can,"thusj"preventing the entrance of and compressing connection between the spout 8 and the standard '12 to'force'said standard downwardly and normally hold thefiexible bottom 2 outwardly'at all times.

A filling funnel 23 is provided with a re- ,duced portion to form ailspout 24:, which'is inserted and secured within the "inwardly and upwardly directed portion 3of the walls l to a point adjacentthe coupling plate 16.
